ACCELERATED DETERIORATION OF TEXTILES
Abstract
Reasons for the difference in photooxidative degradation between cellophane and cotton were investigated. Uranyl oxalate actinometers were used to measure quantitatively the amounts of light transmitted and reflected by the cellophane and cotton. Cellophane containing 0.2% ferric ion, absorbed about 5% of the light. Cotton fabric containing 0.2% ferric ion absorbed more light than the cellophane, but no accurate measurements could be made. Tests were conducted on the acceleration of degradation by heat absorption in cotton and cellophane samples impregnated to equal contents of ferric ion. Tests were on the following degradation accelerators; ferrocene (dicyclopentadienyl iron), dicyclopentadienyl titanium dichloride, ceric ion, and cerous ion. In the limited experiments to date it has been found that cerium, applied to cotton either as cerous ion or as ceric ion, does promote photodegradation.
